Band-Stop Frequency-Selective Surface (FSS) with Elliptic Response Designed by the Extracted Pole Technique.

This paper describes and validates an advanced synthesis design process of Frequency-Selective Surfaces (FSSs) with elliptic band-stop responses. A systematic procedure based on the Generalized Chebyshev Function and the extracted pole technique enables control of the position of the transmission zeros and the attenuation level to obtain an equiripple rejection response. A systematic process is followed to obtain the lumped LC values of the resonator circuits extracted as poles and the impedance inverters.

Cytostatic response of NB69 cells to weak pulse-modulated 2.2 GHz radar-like signals.

The present study investigates the response of two human cancer cell lines to a 24-h treatment with a 2.2-GHz, pulse-modulated (5 µs pulse duration, 100 Hz repetition rate) radar-like signal at an average SAR = 0.023 W/kg, using a newly designed setup for in vitro exposure to radiofrequency (RF) fields.

Design, implementation, and dosimetry analysis of an S-band waveguide in vitro system for the exposure of cell culture samples to pulsed fields.

The interaction between electromagnetic fields and biological media, particularly regarding very high power, short pulses as in radar signals, is not a fully understood phenomenon. In the past few years, many in vitro, cellular communications-oriented exposure studies have been carried out. This article presents a high-power waveguide exposure system capable of dealing with monochromatic, multicarrier or pulsed signals between 1.
